Star Formation Occurs in Competitive Environment

Star Formation Occurs in Competitive Environment

A survey of the stellar nursery in the Orion Nebula Cluster provides evidence that stars compete for material and their size depends on what they gather rather than their initial core size. Plus, NASA mission updates, fast radio bursts, neutron stars, visible novae, and mountain building in the Andes.

The Tibet ASγ Experiment Finds Evidence of PeVatrons

The Tibet ASγ Experiment Finds Evidence of PeVatrons

Using substantial ground arrays and underground muon detectors, the Tibet ASγ Collaboration has captured evidence of ultra-high-energy gamma rays that are thought to be the result of nuclear interactions between cosmic rays and interstellar gas. Plus, OSIRIS-REx, Ingenuity, InSight, comet 2I/Borisov, and things getting hit (or not) by other things.

Betelgeuse Smaller Than Previously Calculated, Still Mystery

Betelgeuse Smaller Than Previously Calculated, Still Mystery

Scientists collected fresh data on Orion’s bright star Betelgeuse to try and understand this star that caused so much controversy last year. They found it’s smaller than previously calculated, and last year’s dimming was likely caused by dust, but it’s also more complex than thought. Plus, galaxies, Earth’s forests, ice on Mars, and Saturn’s moon Rhea.
